Illustrator :: Removing Tints From Brushes

using brushes in Illustrator 5.5, I cannot find a way to change the "tint" of an art brush to a solid color. I have dragged the brush from the brush library to an ai document to try to modify it ...no luck. I have expanded the brush to art outlines ...no luck. I have expanded the transparency. All color and transparency panels indicate 100%, however the object is still a transparent tint. I have tried cutting and pasting the expanded object without luck.
 
I have read the reference manual on this subject, but nowhere does it tell how to remove the tint and make the newly created object a solid color.
